(2013-01-12) Active Directory Schema Discovery PowerShell Script/Tool

Alexandre Augagneur, another directory services MVP, has created/released a PowerShell script that investigates the schema of your AD.

It tells you all kinds of things such as:

Count of attributes created on a specific date;

The date and time the AD schema was created;

The version of the AD schema;

The version of the Exchange schema;

The version of the Lync schema;

The number of schema objects found;

The number of unknown schema objects found;

A full list of schema objects/attributes (this can be exported to CSV to be imported into Excel).

–

You can connect to a local AD forest or a remote AD forest. However for the remote AD forest, your local AD forest must at least have a one-way trust where your local AD forest is the trusted AD forest and the remote AD forest is the trusting AD forest. Before using the tool/script you must download and load a CSV file that contains all the information about the schema objects/attributes and their version information.
